This happen to me a year ago at the Good Social Centre in Dalston. The was a "monster" dominating process by talking over everyone with a steady flow of power politics. I was confronting him about this at a project meeting.

Activists strangely tend to have issues with direct action when it happens in there community's, they sat around looking from one "monster" to the other "monster (me)" making no judgement between the two. In the end he played the Asian "race card" and that was the end of that.

He terrorized and wrecked the space for a year before he was final excluded from space meetings. Sad and bad...

Yes playing the race/gender card can highlight a real issue but sometimes its just more power politics. And if the issue is down to power politics in the first place then this is likely the second not the first reason the "race/gender" card is used to block.

In the case above it turned out that he was a mentally ill, druggie, control freek, with a MBA in bullshit. Sadly he did have real talents, that were key to the project if he could have been helped/supported out of the nasty power politics. This was only fully understood a year latter after he was excluded from the meetings.

Ps. Truth is good, he could have played the "mental illness" card, every one would have agreed and helped him.
